Filed: 1990-05-18
Abstract: PURPOSE:To prevent a line fault due to unsmoothed spectrum of a sent signal string by providing a selection circuit detecting interrupt of reception input and replacing a pattern of the input into a pattern outputted from a code generating circuit to the system. CONSTITUTION:A signal string subject to scramble processing at a host relay station or a transmission end station is inputted to an input interrupt detection circuit 1 and a descramble circuit 2 of a relay station 10. The input interrupt detection circuit l outputs a control signal representing the result of input interrupt detection to a selection circuit 4 and the descramble circuit 2 decodes the received signal string into the signal before scrambling and outputs the result to the selection circuit 4. Then a code generating circuit 3 generates a signal string with a different pattern from a scramble pattern in a radio block and outputs it to the selection circuit 4 and the selection circuit 4 selects and outputs the output of the descramble circuit 2 when the input signal is normal and selects the output of the code generating circuit 3 when the result of detection of the input interrupt detection circuit l indicates input interrupt and outputs it to a scramble circuit 5. Thus, occurrence of a fault in the signal transmission due to unsmoothed output spectrum is prevented.
